Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Brown–Proschan Repair Policy for Repairable Systems Using the Discrete Weibull Failure Distribution and Markov Chains

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT A repairable system operates under a maintenance strategy involving scheduled preventive maintenance (PM) and corrective repair actions following failures. This study develops an exact analytical methodology using Markov chains with discrete states and time to calculate the expected number of failures E[N(t)]$\mathop {\mathbb {E}}[N(t)]$ under

Spectral Submanifolds of Delay Systems: Control in Continuous and Discrete Time

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents both continuous‐time and discretization‐based approaches for constructing spectral submanifolds (SSMs) for time delay systems. The continuous‐time approach built upon sun–star calculus, reformulates the governing delay differential equation (DDE) as an operator differential equation (OpDE).

Energy Security and Sustainability in the GCC: The Conditional and Contested Role of AI and Digital Infrastructure

open access: yesSustainable Development, EarlyView.
ABSTRACT As Gulf Cooperation Council (GCC) economies pursue simultaneous commitments to national AI strategies, renewable energy targets, and Paris Agreement pledges, a key sustainable‐management question remains empirically unresolved: does digital and AI investment genuinely advance energy security and environmental sustainability in hydrocarbon ...
